Transmission of electric energy can be performed relatively easily by fixing both the power supply and the receiving device to the other.

In known transmission devices, for example, electrical energy is radiated from the conductive plates into the gas pipe at high frequencies. Then, the radiated electric energy excites the gas in the gas pipe, whereby the gas in the gas pipe shines.

However, in some electric devices, it is desired that electric energy be transmitted from a fixed power source to a movable body. For example, many generators
It is necessary to transfer electrical energy from the current carrying rotating member to the fixed output terminal, which can be accomplished, for example, by a conductive carbon brush that interacts with the rotating ring or commutator. In this configuration, the electric current generated by rotating the conductor in the magnetic field is transmitted to the fixed electric circuit.

It goes without saying that the motor has the opposite effect to the above.

However, in such an arrangement, some drawbacks associated with transmitting electrical energy from a fixed power source to a movable body by means of conductive terminals (e.g. brushes) are pointed out. There is.

In particular, the conductive brush causes friction due to physical contact with the rotating body, which causes a loss of energy and reduces the efficiency of the system.

A series of electrical circuits is formed through the AC power source, the capacitive link, and the drive member, whereby the current from the AC power source is utilized to cause the neon tube to emit light.

According to another embodiment of the present invention, the transmission device includes an electric motor, and the electric energy is directly transmitted to the motor, whereby the electric energy from the AC power source is It acts to cause the motor to rotate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings.

First, referring to FIGS. 1 to 3, an embodiment of the present invention will be described. A clock 100 embodying the present invention comprises a pair of discharge tubes, for example, neon tubes 102 and 104.
The neon tube functions as an hour hand (short hand) and a minute hand (long hand), respectively.

The neon tubes 102, 104 are attached to the shafts 106, 108 at the center of the clock plane of the clock 100, which allows the neon tubes to rotate, like the hour and minute hands of a conventional clock.

AC electrical energy is a pair of conductive plates.
A capacitive link formed between the gates 122 and 124 and the conductive ring 130 transfers the AC power to the neon tubes 102 and 104. Therefore, the neon tubes 102, 104 are illuminated by the AC electrical energy without causing physical friction between the conductive plates 122, 124 and the conductive ring 130 above the clock plane.

FIG. 1 is a front view of an electric drive clock 100 according to an embodiment of the present invention. The clock includes neon tubes 102 and 104 which serve as hour hands (short hands) and minute hands (long hands). The clock 100 has a circular shape, and the hour and minute hands (neon tubes) 102 and 104 are mechanically attached to the shafts 106 and 108 by arm pieces 112 and 114 at the center of the clock plane of the clock 100. There is.

Both shafts 106 and 108 have a clock 100.
Inside, is mechanically coupled to maintain the compression coil springs 118, 119 in compression. Springs 118, 119
Is configured to move the neon tubes 102, 104 independently by a known clock movement (not shown). Balance plates 127 and 129 are also attached to the shafts 106 and 108, respectively, to balance the weights of the hour and minute hands 102 and 104.

In this embodiment, the minute hand 104 is a conductive ring 13
The hour hand 102 is provided so as to rotate slightly above 0, and slightly below the conductive ring 130. Shaft 10
6 is a hollow body, and the lower part of the small-diameter shaft 108 is inserted into the large-diameter shaft 106 so that the shafts 106 and 108 can rotate independently.

Shafts 106 and 108, arm pieces 112 and 114
Is made of an electrically conductive material such as copper or nickel. In the embodiment, the arm pieces 112, 114 are
The neon tubes 102 and 104 are inserted from the inner ends (the ends facing the center of the clock plane).

In this embodiment, one end of each of the conductive wires 126 and 128 is
The outer ends of the neon tubes 102 and 104 are connected to the neon tubes, respectively, but it is not necessary to connect the neon tubes to the conductive plate with a conductive wire. That is, the conductive plates 122 and 124 are connected to the neon tube 10
It may be directly connected to the outer end of 2,104, and energy loss is sufficiently prevented.

Since the arm pieces 112, 114 and the wires 126, 128 are connected to the neon tubes 102, 104, if a sufficient voltage is applied between the arm pieces, the wires. The gas in the neon tube is excited and glows.

Since the conductive wires 126, 128 are electrically connected to the conductive plates 122, 124, the conductive paths are
Gas 112, 114, gas in neon tubes 102, 104, conductors 126, 128
Is formed between the shafts 106 and 108 and the conductive plates 124 and 126.

The conductive plate 124 is provided above the conductive ring 130, and the conductive plate 122 is provided below the conductive ring 130 with a gap therebetween, and the conductive plates 122 and 124 are substantially parallel to the conductive ring. There is. The conductive plates 122 and 124 are provided so as to overlap a part of the conductive ring 130.

The area of overlap between the conductive plates 122, 124, the conductive ring 130, and the vertical distance between each surface of the conductive plate and the surface of the conductive ring provides sufficient electrical capacity. The value is such that it occurs between the conductive plate and the conductive ring.

For example, the area of the conductive plate 122 overlapping the conductive ring 130 is 1426.8 square mm, and the area of the conductive plate 124 overlapping the conductive ring 130 is 1351.2 square mm. The maximum vertical distance between each surface of the and the surface of the conductive ring is 2 mm.

Here, the conductive plates 122 and 124, the conductive ring
The capacitance (capacitance) C between 130 is given by the following formula. C = eA / d ---- Formula (1) where A is the overlapping area of the conductive plates 122 and 124 and the conductive ring 130, and d is the surface of the conductive plates 122 and 124 and the surface of the conductive ring. The vertical distance between the conductive plates 122, 12
It is a constant determined from the effective permittivity of the substance between the four.

FIG. 2 is a schematic cross-sectional view taken along the center line 150 of FIG. 1, showing the main components of the clock 100.
As shown in FIG. 2, lead wire 156 is electrically connected to conductive ring 130. This lead wire 156 is an AC power supply 16
0 is electrically connected to the output terminal and the ground terminal 162 is electrically connected to the other output terminals of the AC power supply, the output voltage of the AC power supply is the same as that of the lead wire and the ground terminal. Added in between.

A pair of graphite plates 134, 136
And 144 and 146 are provided above and below the springs 119 and 118, respectively. The graphite plates 134 and 136 sandwich the spring 119, and the graphite plates 144 and 146 sandwich the spring 118. And the conductive path is the graphite plate 13
4, 136, 144, 146 and springs 118, 119, respectively (details will be described below with reference to FIG. 3), ground terminals 162 are electrically connected to both shafts 106, 108. It

Therefore, when the AC power supply 160 is connected to the clock 100 by the ground terminal 162 and the lead wire 156, a loop of a complete electric circuit is formed. However, it can also be capacitively connected to the inner ends of the neon tubes 102, 104,
Then, a capacitive connection can be formed, and frictional contact is further reduced, as compared to a mechanical connection in which a spring is sandwiched between graphite plates.

The AC power supply 160 can have various AC waveforms that excite the gas in the neon tube, for example, in the embodiment, the AC power supply has a cycle of 10% (on) / 90% (off).
It is a 1000V peak-to-peak rectangular wave. The frequency from the AC power source 160 is appropriately selected within the range of 100 to 20,000 Hz.

A transformer (not shown) to ensure a high enough voltage to excite the gas in the neon tubes 102, 104.
May be arranged to increase the voltage value of the output from the AC power supply.
This is particularly effective when the known wall outlet is used as the AC energy source.

As can be seen in FIG. 2, an insulating cover 170 is arranged over the conductive ring 130. The insulating cover 170 can be formed from a variety of insulating materials and the dielectric constant of the insulating cover is selected to set the desired capacitance between the conductive plates 122, 124 and the conductive ring 130.

In this structure, the insulating cover 170 functions as a dielectric between the surfaces of the conductive plate 122 and the conductive ring 130. Therefore, the conductive plate 122 having an air gap of up to 2 mm, the conductive ring 130, and the insulating cover 170 located between them as a dielectric become a capacitor in the equivalent electric circuit.

FIG. 3 shows an equivalent electrical circuit 200 for the components of clock 100 of the present invention. As shown in FIG. 3, the equivalent electric circuit 200 includes two electric paths,
These electric paths are provided in parallel with each other and with the AC power supply 160. The first path of the arrow 202 is the neon tube 102.
It is located in series with.

The neon tube 102 is also provided in series with respect to the arm piece 112 shown as the equivalent resistance in FIG. The arm piece 112 (as well as the arm piece 114) may contain carbon within its molding material, in which case the arm piece will be a graphite plate. It functions as a conductive brush that replaces 144.

The arm piece 112 functions as a resistor,
It is embodied by the equivalent resistance in the loop (electrical path) shown in 2.

The arm piece 112 is positioned in series with the graphite plate 144, the spring 118 and the graphite plate 146. Graphite plates 144 and 146 are
Typically, with a measurable low resistance, the spring 118 can exhibit a small inductance.

The second path indicated by arrow 210 is the effective capacitor 20.
8 and this effective capacitor is located in series with neon tube 104, arm piece 114 (shown as an equivalent resistance). The arm piece 114 is a graphite plate.
Port 134, spring 119, and graphite plate 136 are also in series. The graphite plates 134, 136 and the spring 119 are
It has substantially the same electrical characteristics as the graphite plates 144, 146 and the spring 118.

Capacitors 204 and 208 are conductive plates 122 and
It is formed of 124 and a conductive ring 130, respectively. Therefore, the effective capacitances of the capacitors 204 and 208 are calculated by the above equation (1) described with reference to FIG. The dielectric constant e of the dielectric can be calculated as a function of the dielectric constant of air and the insulating cover 170.

The effective impedance of the neon tubes 102, 104 varies as a function of the frequency of the voltage applied to the neon tubes 102, 104 and the current value. Therefore, the neon tubes 102 and 104 function as variable resistors that vary with the frequency of the output signal from the AC power supply 160. The voltage required to excite the neon gas in the neon tubes 102, 104 is
It goes without saying that it depends on the size of 4 and the corresponding volume.

As described above, the clock 100 according to the embodiment of the present invention shown in FIGS. 1 to 3 efficiently transfers the AC electric energy from the AC power supply 160 to the neon tubes 102 and 104. Nevertheless, it reduces the physical contact between AC power supplies and neon tubes. Thus, the clock of the present invention
At 100, frictional resistance for energy transfer can be eliminated.

The graphite plate may be replaced by a pair of capacitive plates, one of the capacitive plates may be fixed and the other may be moved with a corresponding shaft.

As described above, a capacitive transfer method for transferring electrical energy from a fixed body such as the conductive ring 130 to a movable body is based on a power source such as a neon tube 102 driven by another energy source. It can be used to boot a consumable device.

The present invention can be applied to other power consumption type equipment such as an electric motor, and the energy capacitively connected to the power consumption type equipment moves the power consumption type equipment. Figure 4-
In the embodiment shown in Fig. 8, a fan 500 is provided, which is activated by alternating electrical energy from two energy sources 510,520. Conductive fan blades 540, 542,
AC energy is capacitively transferred to the DC fan motor 530 by the effective capacitance created between the conductive flat plates 550, 552.

As shown in FIGS. 4 and 5, the fan 500 is
It has a shaft head 556 placed in the center, which is mechanically attached to the conductive fan blades 540, 542 so that when the shaft head rotates,
The conductive fan blade also rotates to stir the air.

Shaft head 556 is mounted on a rotatable shaft 560 (see FIG. 5) extending from motor 530. Lead wires 564 and 566 are conductive fan blades 540 and 542.
Are electrically connected to the
Connected to the 530. FIG. 7 shows the motor 530.
The details will be described later.

Fan blades 540 and 542 are mounted for rotation on a pair of conductive flat plates 550 and 552. The fan blades 540 and 542 are separated from the upper surfaces of the flat plates 550 and 552, and the fan blades 540 and 54 are
The lower surface of 2 is parallel to the upper surface of the flat plate.

In the embodiment, the lower surfaces of the fan blades 540 and 542 are substantially flat, and the relatively constant distances are the lower surfaces of the fan blades 540 and 542 and the flat plates 550 and 552.
Secured between the upper surfaces of. Flat plate 550, 55
2 is electrically connected to AC power supplies 510 and 520 by lead wires 570 and 572, so that AC energy is supplied to the flat plate.

When a part of the fan blades 540 and 542 reaches directly above the flat plates 550 and 552, electric capacity is secured between the fan blades and the flat plates. If the average value is taken as the vertical distance between the lower surfaces of the fan blades 540 and 542 and the upper surfaces of the flat plates 550 and 552, and assuming that they are substantially constant, their capacity can be calculated from equation (1). .

The constant e of the permittivity is determined by the fan blades 540 and 54.
2. Depends on the medium between the flat plates 550 and 552, such as air or liquid. The fan blades 540, 542 or flat plates 540, 542, or the flat plates 550, 552 are changed so as to change the dielectric constant of the dielectric.
The belts 550 and 552 may be covered with an insulating member.

As a practical matter, when the fan 500 rotates, the fan blades 540, 542, the flat plates 550, 552
There is a slight variation in the vertical distance between the. Even with such variations, a relative small variation in the vertical distance between the fan blades 540, 542 and the flat plates 550, 552 causes a slight variation between the fan blades and the flat plates. It has been found that it does not significantly change total capacity.

Fan blades 540, 542, flat plate
The variation in distance between 550 and 552 is equal in magnitude,
This is the result because the directions are opposite. For example, if the fan blade 540 has a flat
As it approaches 550, it is symmetrically located on the other side of the fulcrum shaft head 556, so that the other fan blades 54
The two are separated from the flat plate 552 by the same distance.

Therefore, the capacity between the fan blade 540 and the flat plate 550 increases, and the capacity between the fan blade 542 and the flat plate 552 decreases.

It can be mathematically understood that the total capacitance of these effective capacitors remains substantially constant with slight variations in distance. That is, an increase in capacity in one fan blade / flat plate combination compensates for a decrease in capacity in the other fan blade / flat plate combination, thereby maintaining a constant total capacity. To be done.

Fan blades 540, 542, flat plate
Due to the capacity between 550 and 552, the AC energy is transferred from a fixed flat plate 550 and 552 to a movable fan blade 54.
0, 542, and finally to the motor 530. The power delivered to motor 530 is a function of the frequency of its AC energy and the capacity between fan blades 540, 542 and flat plates 550, 552. for that reason,
If the total capacity is maintained constant, the power transmitted to the motor 530 will cause the frequency of the AC energy supplied to vary.

The AC energy is supplied from the AC power supplies 510 and 520 to the flat plates 550 and 552 via the lead wires 570 and 572, respectively. The AC power supplies 510, 520 can have an AC waveform that can start a DC motor when rectified.

For example, the AC power supplies 510 and 520 may be 800V peak-to-peak rectangular waves having a 50/50 duty cycle as shown in FIG. It is convenient to use a low peak-peak voltage of about 240V.

The frequency supplied by the AC power supplies 510, 520 is preferably in the range of 20-100 Hz. As shown in FIG. 6, the output voltages from the AC power supplies 510 and 520 are 180 ° from each other.
It is considered to be out of phase. Then, the positive voltage of the same amplitude is always applied to either of the flat plates 550 and 552, so that the rectifying circuit for the DC motor 530 is not necessary.

The AC energy acting on the flat plates 550, 552 is capacitively connected to the conductive fan plates 540, 542. This AC energy is
Via leads 540 and 542, lead wires 564 and 566 to the motor
Supplied to 530, rotating shaft 560.

When the fan blades 540 and 542 rotate, the fan blades cross the surface of the flat plates 550 and 552. Fan blades 540 and 542 are flat plates 550 and 55
When crossing 2, the electric capacity is generated and the AC energy is transferred from the flat plates 550 and 552 to the fan blades 540 and 542.
Is transmitted by the rotation of the fan blade.

That is, each time the fan blades 540 and 542 rotate and reach the flat plates 550 and 552, AC energy is transmitted to the flat plates 550 and 552.
Although only a pair of fan blades 540 and 542 are shown, it is possible to arrange more than three fan blades, for example, three pairs of fan blades to set a continuous overlapping area with the flat plates 550 and 552. Needless to say.

In this configuration, a capacitive link is formed between the fan blades 540, 542 and the flat plates 550, 552, thereby delivering a continuous pulse of energy to the fan motor 530. .

As described above, the power transmitted to the DC motor 530 is a function of the frequency of the applied voltage. In detail, the power transmitted to the motor 530 fluctuates in proportion to the frequency of the applied voltage. That is, as the frequency of the applied voltage increases, the power transmitted to the motor 530 also increases.

Further, since the speed of the DC motor 530 increases in proportion to the input, the speed of the motor increases as the frequency of the applied voltage increases, and the rotation speed of the fan 500 is the AC power supply 510. , 520 depending on the frequency of the output voltage.

FIG. 7 is a schematic cross-sectional view of the main members of the motor 530. The motor 530 has a shaft 560 which extends downward through the center of the motor. Lead wire
566 and 564 extend downwardly from the shaft 560 and connect to the motor 530, forming a conductive loop 570 around the shaft. The shaft 560 is supported by a bearing 575 so as to be rotatable in the axial direction.

The motor 530 includes at least a pair of fixed magnets 58.
The fixed magnets 580 and 582 are N poles and S
Since the poles are arranged to face each other, the line 58 in FIG.
A magnetic field is formed across the loop 570 as indicated at 5.

When an electric current flows through the loop 570, the electric current becomes a magnetic field.
585 interacts with it to produce a force normal to the plane in which the current flows and the magnetic field lies (in the example, the plane of the drawing).

This force rotates the shaft 560 and the shaft head 556 and fan blades 540 and 542 also rotate. Therefore, the present invention provides a device for capacitively transmitting electric energy from a fixed power source to a movable body such as a motor.

FIG. 8 shows a schematic diagram of an equivalent circuit 800 of a fan embodying the present invention. The equivalent circuit is provided with a series path having a power supply 510, and the power supply is an effective capacitor 810 and a fan motor.
It is provided in series with 530, the effective capacitor 812, and the power supply 520.

The capacitors 810 and 812 are fan blades 54
0, 542, and flat plates 550, 552, respectively, and the effective capacitors 810, 812 are calculated from the above equation (1). Here, the permittivity e of the dielectric is the fan blade 54
It is calculated as a function of the dielectric constant of air, liquid, etc., which is an insulating medium between 0, 542 and flat plates 550, 552. The fan blades 540 and 542 rotate and the flat plate 55
When moved from above 0,552, capacitors 810,812 open an electrical circuit.

As described above, the fan that is a specific example of the present invention provides an apparatus and method for capacitively transmitting AC electric energy to a motor without causing physical frictional contact with a brush or the like. To do.

The above fan is only an example of a DC motor that is capacitively connected according to the techniques of this invention. That is, the above-described embodiments are for explaining the present invention, and are not intended to limit the present invention at all, and all modifications and alterations made within the technical scope of the present invention are also included in the present invention. Needless to say.

For example, the above-described clock embodied as the first embodiment may be modified so as to adopt only the hour hand of the neon tube, or may be modified so as to additionally have the second hand of the neon tube. May be. An electrically actuated motor may be used in the example clock instead of the spring-loaded clock movement.

The second embodiment embodied as a fan may be modified to operate using only a single power source. Furthermore, as another embodiment, the present invention can be embodied in a device having a movable member that transmits an AC power source to a power consuming electric device. For example, the technique of the present invention can be incorporated into a boxed large timepiece (grandfather clock) having a conductive pendulum or a Merigo land.

[0083]

As described above, according to the present invention, AC electric energy is capacitively transmitted to a movable body such as a clock or a motor without causing physical frictional contact by a brush or the like. A device and method for doing so can be obtained.

Since there is no physical contact, friction does not occur,
There is no loss of energy due to friction or system efficiency.

Since there is no wear due to friction, member replacement is unnecessary. And since there is no replacement of parts, the cost does not increase.
